Five soil profiles were sampled around a uranium waste rock dump in South China, which included two unpolluted and three potentially uranium-polluted pro- files. Through the comparison of the uranium distribution characteristics and the analysis of the uranium chemical forms of these profiles, the following conclusions can be drawn: (1) significant uranium pollution to the surrounding soils was caused by the dump, and the average uranium in these soils, such as the profiles WP1, WP2 and WP3, was 633.6, 9 and 2.7 times more enriched than the background value; (2) the exotic uranium, which was preferentially aggregated in the upper layer of the soils near the pollution source, would be gradually precipitated in the lower layer of the soils away from the pollution source; (3) the input flux of the exotic uranium of each chemical form would be larger in the soils closer to the pollution source.
